Definitions

  • a fourth aspect of the present invention is a disc-shaped data record medium for recording first sectors composed of first data divided by a length of a multiple of 512 bytes or second sectors composed of second data divided by a byte length corresponding to a CD format, an error-correction-code encoding process and a digital modulating process having been performed for the first sectors or the second sectors, a header being added to each of the first sectors or the second sectors, the header being used for identifying whether the sector containing the header is the first sector or the second sector.
  • Both a sector format with a data length of a multiple of 512 bytes (for example, 2,048 bytes) and another format with a byte length corresponding to the CD format (for example, 2,352 bytes) can be handled with physical regions.
  • computer storage data and CD-ROM data can be stored on the same record medium.
  • one sector of computer data contains data of 2 kbytes.
  • one sector may contain data of a multiple of 512 bytes.
  • the sector contains a data sync (2 bytes), a header (8 bytes), and an error detection code (4 bytes) as well as user data (1,024 bytes).
  • the header is composed of a CRC (that detects a header error) (1 byte), copy management information (CGMS) (1 byte), layer information (1 byte), an address (4 bytes), and auxiliary data (1 byte) that are the same as those shown in Fig. 6B.
  • Fig. 16 is a block diagram showing an error correction code encoding process performed by the error correction code encoder 8.
  • the error correction code is similar to the cross interleave Reed-Solomon code used for a CD (this code is used in the folding type dual code encoding process).
  • Figs. 19A, 19B, and 19C show examples of data sync patterns.
  • Fig. 19A shows the case of which all "1s" are assigned to the data sync pattern for the 2 kbyte sector format and all "0s" are assigned to the data sync pattern for the CD sector format. In this case, the distance between two bit patterns becomes maximum.
  • the error correction code encoding/decoding processes and digital modulating/demodulating processes can be commonly used for two types of sector formats, the hardware scale can be reduced. Moreover, software data for a computer and software resources for a CD-ROM can be handled on a single record medium.
